Go support is still very limited, and Swift support doesn't seem to exist at all. So they try with yet another language. The main difference is that this is a crappy language with $php $jquery $syntax.

The main difference is kotlin runs on the jvm and mixes with all the other java just fine, so all they're doing is shipping android studio with support for it. The support that was already in IntelliJ presumably. What else do they need to do?

Someone watched a Google IO event? Boring shit shows with engineers half-heartedly giving presentations and a team of professional cheerers sitting behind the three rows of trade press audience busy with their phones.
